Design of a Reconfigurable Superdirective Antenna for Wi-Fi Module

This paper is a model of a reconfigurable superdirective antennas. The array antennas is made for Wi-Fi module in 2.45GHz ISM band. Monopoles, two-by-two linear and 0.1λ spaced, set on a Fr4 substrate respecting 40mm radius of a circular Wi-Fi module. Differents configurations are established with passive components directly integrated to antennas with pin diodes. The obtained results show that properly integrated, array antennas can maintain compared to simulation a reconfigurable superdirectivity with a gain in order of 5.2dB in four directions of azimutal plane and significantly increase its radiation efficiency.
